Bunker With Adjoining Tunnel Systems
Feb 10 2010, 8:37 AM EST
Okay so here it is.I am designing a small fortress made from concrete buildings and Hurricane fencing walls and gates. Now the idea of this is to be realistic and not like the Bar. So there will be a few things that I will be needing advice on. But first here is the basic layout: Inner compound has 5 buildings: 1 Main Fortress in the centre, which has a tall tower with a snipers nest at the top, plus 4 bunkers towards the 4 corners of the fortress. The bunkers are half sunk underground as is the fortress. All these buildings are connected by a series of underground tunnels which also link into an underground garage area. WHAT I NEED: How many people should i design the compound for, as i want to get as many people as possible into it, plus anything else you can think of really. This is meant to be a "serious" constructing plan, and would be completed pre-zday so all the buildings and tunnels would be made from concrete. Designs to follow once completed. I am aiming for approx. 60 people at the moment so use that as a base for your figures. other than that go nuts my friends!! 6 out of 8 found this valuable. Do you? |

"1. How are you funding all this?Its going to be built on a large plot of land I am already looking at purchasing, has no inhabitants for close to 100 kilometers around except for the odd neighbor. The land is located in New South Wales in Australia, where I am from basically, and the compound itself is the actual revenue generating machine as I intend to start my own "survival week" sort of thing from it, instructing in normal survival and combat weekends, employing ex-military members from all over the world as instructors. And no this is not some teenage fantasy thing, I'm an actual adult, just go the heart of a kid! As for how much it will all cost I'm not sure yet as I'm still in the early planning stages, but my cousin is a contractor and would be able to do it for me on the cheap so that will help. 3 out of 3 found this valuable.

I like it. Although I wouldn't consider calling any high towers 'sniper's nests' since they will be more for observation day to day.You should plan for a min of 50 people and potential 100. Also consider: infirmary/medical area swimming pool/recreation area/gym meeting halls storage areas several kitchens, lavatories and laundries 9 out of 9 found this valuable. Do you? |

Building stuff is easy, logistics and infrastructure is the PITA part. - Power: You will need energy. In my opinion, electricity is very important in maintaining any colony. Electricity can be produced by fuel-driven motor generators, water, wind, or solar. The first two are more constant, the second two can easily have "dry spells." Fuel is also very important in my opinion. Some of the ways to produce usable fuel are with an oil well, or by rendering plants to produce vegetable oil. - Water and Food: You will need a steady source of water. Consider drilling wells or damming up a local stream. Streams are useful because they can produce hydroelectric power as well as fresh water. You will need food. A vegetable garden and animals will work. Goats, chickens, and sheep are good animal choices. Ensure you have grazing land. - Sanitation: You will be producing waste. "Grey water" (from sinks, showers, and laundry) can be used to irrigate crops or store in fire-suppression tanks. "Black Water" (from toilets) can be processed in a septic system. When designing your fortress, plan for two separate sewer systems, one for grey water that funnels into a storage tank, and one for black water the funnels into an underground septic tank with leech lines. You will also be producing solid waste (trash). Consider building an incinerator to use any flammable trash (paper, wood scraps, etc) to heat water. Any non-recyclable or non-flammable trash (should you build an incinerator) should be disposed of far from your fortress to reduce chance of disease or unsightly piles. Green waste can go into a compost heap to fertilize crops. This includes most table scraps, coffee grounds, egg shells, tree trimmings, etc. - CONT. 5 out of 5 found this valuable. Do you? |

- Other Issues: If you are running this as a business pre-apoc, you will need to meet commercial building, fire, safety, and handicap codes. This means wheel-chair ramps, fire sprinklers, proper electrical, Exit signs, etc. You should work the purchase of a backhoe into the building cost. Renting one for the subterranean tunnels, building footings, wall footings, and road construction would be pricey, and you might as well have one around all the time. I have one at my BOL and it is very useful. Wall construction: Consider building earthen walls. This is a concrete wall, with a big pile of dirt behind it. It is far stronger than a concrete wall alone, as the dirt mound buttresses the wall against outer force (say, raider's vehicles hitting it, or enemy fire) FM 90-10-1 states the concrete penetration distances for 7.62 and .50 BMG. Between 2" to 4" will stop a single round, so about a foot of concrete on exposed building walls (especially the sniper tower) should be good. Vehicles: I don't know about you, but I say vehicles make life way easier. I would incorporate at least a single stall garage with a 4 point Rotary lift in your design. Give you a good place to maintain your motorpool. Other suggestions: Firing range. Perhaps even a mock CQB area with plywood "rooms" to train in. Sparring mat for martial arts, maybe include an "all in one" weight machine and a kickboxing bag. Dormitories: When housing multiple survivors or students, it would be more space-effective to house them in barracks-style areas with bunks. "Safe-Room" - basically a bomb shelter. Doesn't have to be comfy, just has to be underground and hardened against radiation and pressure. Sure would suck to be all prepared, and not have a last resort option should government-sponsored carpet-bombing commence. 7 out of 7 found this valuable. Do you? |

thanks all these suggestions have been majorly helpful.I will put in some designs i have already drawn up, before i started the thread) to show what I already have and work from there. Might get people to show their design versions too to get a sort of "community bunker" idea going. Do you find this valuable? |

jay: Stryker has laid out more detail than I, however, have you considered a 'layered' defense beyond the final hard point of the complex wall line?I presumed you'd have a motor pool (a functioning garage area/maintance bay) and areas for food. Also, a secured water supply. Both fuel and water should have gravity feeds to conserve power. Do you find this valuable? |

"jay: Stryker has laid out more detail than I, however, have you considered a 'layered' defense beyond the final hard point of the complex wall line?"I agree with this totally. You have your compound and buildings, and then the wall, and then outside the wall you should have earthen ditches and mounds with concertina wire and fences. There's no good reason to give your enemy an easy ground to fight on. 1 out of 1 found this valuable. Do you? |

New guy here. Um, let me try and make this easier. Instead of building this go and find it. Abandoned State hospitals of yore have large strong buildings with a multitude of buildings and usually some kind of fence around the perimeter. They also are usually all connected by underground tunnels, have there own power plant on site (which may need work) and a ton of old equipment left behind. Just a thought.

basically your making a city underground so why not make your own version of Coober Pedy,

"basically your making a city underground so why not make your own version of Coober Pedy, "yeah that is the basic layout idea of everything but i still want a sizable above ground fortress so as to see what's coming and to let other know that there is a surviving population there. Plus it allows me to make defense far easier too e.g. If i can see any approaching raiders or zeds i can take them out before they get too close, versus having a horde swarm into the underground systems compromising the main defense of the whole compound.

"of course, ive made small forts like that when i was a kid, granted the were out of cardboard & plywood, but i know that you need the above ground for main defense, i would suggest for early warning/ way of slowing down zed & raiders, constintina wire & razor wire/ snag wire topped fencing.The constintina wire will cut up flesh like it tissue paper & the razor/snag wire combo will cut & intangle anyone trying to climb the fence Do you find this valuable? |

I had a couple of thoughts, 1- Why are the bunkers going to be half underground? I would prefer to have Z's on four sides, not five 2- I think a survival week as a business is a great idea. That being said, If I had gone to this place as a customer, and the Z's rise, I'm am going to do everything in my power to get there. That could cause a lot of unwanted visitors. Maybe use the initial as a business, setting it up somewhere closer to a city making it easier for customers to get there. Then using profit from that one, build another just for you and your group. 2 out of 2 found this valuable. Do you? |

"1- Why are the bunkers going to be half underground?

Guess I was thinking of a different kind of bunker (short, squat, firing port to the front)You could also use watchtowers. I have a picture of one that would be perfect for this kind of thing. Not quite sure how to send it though. Do you find this valuable? |

If you put the bunkers partially underground and you do have any firing holes or "windows" of some sort then you should make hallways with thick steal doors that seal from the "main chamber". That way if one of the bunkers is compromised, you can seal it off and hopefully not lose the whole base.I think you will need to worry about water and food first. Is it a good location for growing some crops, or does it have access to water, above or not to far below ground? That is the real important stuff. If you run out of that, you won't survive very long. 2 out of 2 found this valuable. Do you? |

That way if one of the bunkers is compromised, you can seal it off and hopefully not lose the whole base.The steel doors is in the designs already but im glad someone brought it up just so i could verify that it was a good idea. as with the water and food situation thats the one im having the most trouble with. If i am to use this as a business before hand I cant have the fields to grow crops cluttering up the "military" feel of the base and water is obviously a huge issue in australia, the best i could come up with for now is storm water run off tanks and huge damns to use as catchments Do you find this valuable? |
